Bacula comes by night and sucks the vital essence from your computers.

Bacula is a set of computer programs that permit you (or the system
administrator) to manage backup, recovery, and verification of computer
data across a network of computers of different kinds.  In technical
terms, it is a network Client/Server based backup program.  Bacula is
relatively easy to use and efficient, while offering many advanced
storage management features that make it easy to find and recover lost
or damaged files. Due to its modular design, Bacula is scalable from
small single computer systems to systems consisting of hundreds of
computers located over a large network.

bacula-server contains the bacula-sd "storage daemon" that writes the
backup data to the backup device.  bacula-dir is the "director" that
manages backups.  bconsole is the management application to control the
director and get status of file daemons and storage daemons.
